JUSTIN J. WILLIAMS, OF MOUNT JEWETT, PENNSYLVANIA.

AUTOMATIC LAMPBLACK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 601,389, dated March 29, 1898. Application filed September 21, I894. Renewed July 29, 1897. Serial No. 646,412. (No model.)

To aZZ whom it may concern:

Be it known that I, JUSTIN J WILLIAMS, a citizen of the United States, residing at Mount Jewett, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Lampblack-Machines, of which the following is a specification.

The object of myinvention is to provide a compact, etficient, and durable apparatus for producing lampblack and overcoming the difficulties incident to the machines now in use. Heretofore the temperatures of the depositplates were regulated by means of water, which is found to be very objectionable. Furthermore, the scrapers were passed back and forth over the plates, which prevented an even deposit on them and also tended to lessen the life of the plates. '1 overcome these ob- .jections by the mechanismhereinafter described, and which consists, essentially, of a chamber located over the deposit-plates, and through which air is passed, and of the automatic means connected with the scrapers for withdrawing them from the plates at the ends thereof and then bringing them in contact therewith at the beginning of the plates.

Myinvention further consists of certain features of novelty that will be hereinafter fully described, with reference to the accompanying drawings, which form a part of this specification, and specifically pointed out in the claims.

In the said drawings, Figure 1 is a front elevation of my device. Fig. 2 is a top plan view of two apparatuses connected together and operated by means of a rack and pinion. Fig. 3 is a side elevation of the device shown in Fig. 2, showing an end collecting-boot and scraper, together with the mechanism for operating the same. It also shows an inner collecting boot, partly in section, in order to show the tilting bottom. Several of the deposit-plates are removed in order that the rack and pin); on which operates the scraper and collecting-boots can be seen. Fig. 4: is an enlarged View of an end collecting-boot in cross-section, showing in dotted lines the mechanism for-operating the scraper. Fig. 5 is an enlarged cross-section view of a depositplate and showing the manner of mounting the scrapers and collector-boots thereon. Fig.

- 6 is a top view of one of the deposit-plates,

partly in section, to show the joint of the plates; and Figs. 7 and 8 are respectively a side and end view of the plate shown in Fig. 6.

In the said drawings, 1 represents the upright pipes of the supporting-frame; 2, the trusses, which are supported on the pipes l by means of bosses 3, which enter the ends of the pipes, and 19 and 20 are the cross-pipes of the frame. I

4 represents the deposit-plates, provided with flanges 52 and supported from the trusses 2 by means of the flanges 8, formed on said plates in any suitable manner. The flanges 8 (see Fig. 7 are L shape in form and also serve for the purpose of bolting them together to connect the plates when it becomes necessary. (See Fig. 6.) The plates 4 are also formed with chambers 5, preferably of semicircular form. These chambers are designed to have air passed through them to regulate thetemperature of the plates, it being forced into them by means of a rotary fan (not shown) through pipes 7 and allowed to escape at the opposite ends through pipes 51, the temperature being regulated by the amount and the speed of air passing through the chambers.

By employing air to regulate the temperaferior quality. By the use of air the black is kept dry and rust is avoided.

9 represents the collector-boots, which are supported from the flanges 52 of the plates l by means of the frame 11, which is secured to the gibs 10, resting and sliding on the said flanges. These collectors are placed under each plate and are connected together, as shown in Fig. 1, and they are also provided with plates 50 (see Fig. 5) to prevent any of the black being lost and are moved along under theplates, together with the scrapers, which are located Within them, by means of the rack 12, which is moved by the pinion 13, mounted on the shaft 14, driven by any suitable means. The device shown in Fig. 3 consists of two apparatuses composed of a number of plates arranged as shown, which arrangement I have found the most economical and in which as the scrapers on one apparatus are collecting from the plates the scrapers on the other apparatus are withdrawn from the plate and are being returned to the beginning of the plates. The black collected is dropped into the trough from the collector-boots 9 and conveyed through pipes 16 by means of the worm conveyer 17, mounted on a shaft 18, to a receptacle provided for it.

28, Fig. 5, represents the scrapers, located in the collectors 9. These scrapers fit in slotted boxes 29, secured to the ends of levers 30, which are pivotedin lugs 31 on the frame 11. 32 represents weights located on the outer ends of the levers and adapted to normally keep the scrapers against the plates 4. 33 represents an angle-iron on which the levers 30 rest, and secured to the angle-iron is a bar 34, provided with a slot 35, in which a pin 36 on the collector 9 fits. A lug37 is also formed on this arm 34, which fits in a slot 38 of a weighted disk 39, pivoted on a rod 44, located in the collectors 9. These weighted disks are only placed on the end collectors (see Fig. 1)

- and they are formed with the weight 42 and the lugs 40 41.

43 is a swinging lever loosely mounted on the rod 44, and 45 is a tie-rod connected at its respective ends to the lever 34 and frame 11 for sustaining the angleiron 33 in its proper position during any movement of the lever 34.

The operation of the above-described mechanism is as follows: As the scrapers are moved along under the plates they are held in engagement with them by the weighted lever 30. As the scrapers near the end of the plate the lever 43 is engaged by a pin 46 on the trough 15 and moved into engagement with the lug 40, which causes the lever to force the disk 39 to turn, and as it turns the lug 37 moves in the slot 38, and a further movement of the scraper to the position shown in dotted lines,

Fig. 4, forces the lever 34 upward, which causes the scrapers to be withdrawn from the plates 4. (See Fig. 4.) The scrapers are held .in this position owing to the weight on the disk-holding it in the position shownby dotted lines, Fig. 4. As the scrapers are m ved back to the beginning of the plates by the rack and pinion the lever 43 is engaged by a second pin 47, which throws the parts back to their normal position and allows the scrapers to engage'the plates 4.

Thus it will be seen that by. the above-described automatic mechanism the scrapers only work in one direction, this being an important feature in manufacturin glam pblack, as it allows each burner an equal period to make its deposit, and a uniform thickness of lampblack will be on the plates when they are working and all unnecessary wear on the plates avoided.

In each of the collectors I locate a bottom 48, loosely mounted on the rods 44 and provided with a depending lever 49, which engages with the trough 15 in order to tilt the bottom and allow the black to fall into the trough.

21 represents a cross pipe-fitting in which the main gas-feed pipe is connected, and 22 are cross feed gas-pipes which are supported on the cross-pipes 19 by means of the blocks 22 and which are connected with the central pipe 24. In the cross feed gas-pipes are secured the upright pipes 25,which support the burner-pipe 26. The burners 27 are set at any distance from the deposit-plate that may be considered desirable.

In Figs. 7 and 8 I have shown a modification of the means of connecting the air-pipes 7 with the plates 4, the plates being formed with the detachable head in which the pipe 7 is secured.

Having thus described my invention, the

following is what I claim as new therein and desire to secure by Letters Patent:

1. In a lampblack-machine, the combination with'a suitableframe, a series of depositplates, each provided With a cooling-chamber on its upper surface, a series of collectors movably mounted and under said plates and provided with a movable bottom, a conveyer carried by said frame located at the ends of the plates and into which the collectors empty, and suitable means for tilting the bottoms of the collectors when they reach the conveyer, substantially as shown and described.

2. In a lampblack-machine, the combination with a suitable frame of a series of deposit-plates provided with cooling-chambers on their upper surfaces, suitable side flanges formed on the'plates and the L-shaped flanges on the ends thereof, the collectors for said plates and the scrapers, s ubstantially as shown and described.

3. In a lampblack'machine, the combination of the frame, the deposit-plates mounted on said frame, the scrapers therefor, and suitable automatic means for withdrawing them from and returning them to engagement with the plates, consisting of a weighted lever connected with the scrapers, a weighted disk connected with said lever, an arm carried by the disk, and adapted to engage with suitable means located at each end of the plates, substantially as shown and described. I

4. In a lampblack-machine, the combination of a frame, a series of deposit-plates mounted on said frame, a series of scrapers for said plates adapted to be automatically withdrawn from and brought into engagement with said plates, a series of collectors for said plates provided with a movable bottom, and suitable means for tilting the bottoms of said scrapers, substantially as shown and described.
